Leinster make three changes to their pack for Saturday's Heineken Champions Cup tie against Racing 92 at the Aviva Stadium, live on RTÉ2 and RTÉ Player.
Ireland internationals Rónan Kelleher, Joe McCarthy and Jack Conan all start as Leinster target a 16th successive victory which will secure home advantage in the knockout stages.
Caelan Doris, who scored a try, created two more and was sin-binned in last weekend’s win over Gloucester, moves to blindside flanker as Conan comes in at No 8.
McCarthy partners James Ryan in the second row while Kelleher, who came off the bench to score a try against Gloucester, is preferred to Dan Sheehan at hooker.
Sheehan, Ross Molony and Ryan Baird all drop to a replacements bench that includes six forwards and two backs.
Ross Byrne and Jamie Osborne are retained at out-half and inside centre respectively, having been called up by Ireland head coach Andy Farrell for the Six Nations.
Scott Penny will make his Champions Cup debut if introduced from the bench.
Leinster: Hugo Keenan; Jordan Larmour, Garry Ringrose (capt), Jamie Osborne, Jimmy O’Brien; Ross Byrne, Jamison Gibson-Park; Andrew Porter, Rónan Kelleher, Michael Ala’alatoa; Joe McCarthy, James Ryan; Caelan Doris, Josh van der Flier, Jack Conan.
Replacements: Dan Sheehan, Michael Milne, Cian Healy, Ross Molony, Ryan Baird, Luke McGrath, Harry Byrne, Scott Penny.
Ireland internationals James Hume, Stuart McCloskey and Billy Burns are restored to the Ulster backline for Saturday’s must-win match against Sale Sharks.
Dan McFarland makes seven changes to the team that suffered a last-gasp loss to La Rochelle, with Hume and McCloskey resuming their midfield partnership and Burns replacing Ian Madigan at out-half.
Academy back row Harry Sheridan makes his full debut after coming off the bench against La Rochelle. He starts at blindside flanker in place of Iain Henderson, who misses out due to concussion.
Andy Warwick, Tom Stewart and Sam Carter also come into the pack, with Alan O’Connor taking over the captaincy.
Ulster: Michael Lowry; Rob Lyttle, James Hume, Stuart McCloskey, Jacob Stockdale; Billy Burns, Nathan Doak; Andy Warwick, Tom Stewart, Jeff Toomaga-Allen; Alan O’Connor (capt), Sam Carter; Harry Sheridan, Nick Timoney, Duane Vermeulen.

John Ryan and John Hodnett come into the Munster pack as Graham Rowntree makes two changes to his starting line-up for Sunday’s trip to Toulouse.
Ryan starts at tighthead in place of Roman Salanoa, who drops to the bench, while Hodnett comes in for the suspended Jack O’Donoghue in the back row.
Joey Carbery, who was left of Ireland’s Six Nations squad, continues at out-half with Jack Crowley retained at 12 after shaking off an ankle injury.
Munster skipper Peter O’Mahony shifts to blindside flanker to accommodate Hodnett’s inclusion at openside.
Malakai Fekitoa could make his Champions Cup bow for the province after being named on the bench alongside Conor Murray and Ben Healy.

Cathal Forde is retained at inside centre after scoring three tries in two games while fit-again Adam Byrne and Conor Fitzgerald come into the backline.
Denis Buckley and Shane Delahunt pack down alongside Finlay Bealham in the front row, Leva Fifita partners Josh Murphy in the second row, with Shane Hurley-Langton named at blindside flanker.
